White on rice, again

: Hi all. I searched the archives and googled, but cannot find the origin of the expression "like white on rice". My sister insists that it is a racial expression and not to be used by polite society.

: I understand the meaning, it's the origin (and whether or not it's racist) in which I am interested.

: Thanks!

My opinion: it's not racist. Ike Turner, an African-American, was the first person I heard say it and I, a European-American, was not offended. Sometimes rice is just rice. White on rice is just a cleaned up version of "stink on sh*t."
